Oh, let's not throw the whole plant under the bus here - might just have been the Ramen noodle lunch bell going off as he was torqueing down the clutch nut!
I knew a guy, went to lunch, forgot to put oil back into the county's $12,000 riding mower. Sadly, they didn't fire the idiot - I had to work with him for another friggin' 15 yrs.
